This is one of those things that I should know, but don’t. Any readers able to help?
For our non-boating friends, in Americanada when you are in “the open” and you want to enter “a harbor” (fuzzy concepts that get very confusing when you have two harbors connected by a channel) you keep the red buoys on your right side and the green buoys on your left side to avoid any crunchy bits touching your boat. This buoy coloring fact spawned the mnemonics “red right returning” and “red left leaving”. Major buoys in the ocean often also have lights that flash in certain patterns so they can be identified, loud sounds and have stuff built in so that they show up as larger-than-they-are blips on your radar screen – all so that mariners can find their way to safe harbors in the dark and in the fog.
To my question for the boaters: It seems to me like the red buoys out here on the W Coast moo and the green buoys clang like a cowbell. Is it just the case that some buoys have bells and some have horns and randomly I’ve been seeing red ones with horns and green ones with cowbells or is this a planned fact that you can use to guide yourself into the harbor in the fog?
